84 eDisplay (OP7200)
Prints a formatted string (much like printf) on the LCD screen. Only the character codes that exist in
the font set are printed, all others are skipped over. For example,
'\b', '\t', '\n', and '\r'
(ASCII backspace, tab, new line, and carriage return, respectively) will be printed if they exist in the font
set, but will not have any effect as control characters.
Any portion of the bitmap character that is outside the LCD display area will be clipped.
PARAMETERS
x is the x coordinate (column) of the upper left corner of the text
y is the y coordinate (row) of the left top corner of the text
pInfo is a pointer to the window frame descriptor
fmt is a formatted string
... is a formatted string of conversion parameter(s)
EXAMPLE
glprintf(0,0, &fi12x16, "Test %d\n", count);
SEE ALSO
glXFontInit
Sets the glPrintf() printing step direction. The x and y step directions are independent signed val-
ues. The actual step increments depend on the height and width of the font being displayed, which are
multiplied by the step values.
Use glGetPfStep() to examine the current x and y printing step direction.
PARAMETERS
stepX is the glPrintf x step value
stepY is the glPrintf y step value
SEE ALSO
glGetPfStep
Gets the current glPrintf() printing step direction. Each step direction is independent of the other,
and is treated as an 8-bit signed value. The actual step increments depends on the height and width of the
font being displayed, which are multiplied by the step values.
Use glSetPfStep() to control the x and y printing step direction.
RETURN VALUE
The x step is returned in the MSB, and the y step is returned in the LSB of the integer result.

char *fmt, ...);
